[4] The infrasonic sensing array contained a minimum variance distortion-less response beam former to enhance the detection and estimation performance of the acoustic system by improving the signal to noise ratio.
The main obstacle in the detection and analysis of infrasonic signals was the intrinsic pressure fluctuations due to air turbulence/wind noise, which was always present.
These hoses make the filter's instrument response and wind–noise reduction uniform for all signals and wind directions, simplifying the array process.
Information obtained with the research of infrasonic sensing arrays lead to the development of The Unattended Transient Acoustic MASINT Sensor (UTAMS) computer carried by the Aerostat of Persistent Threat Detection System (PTDS), which was an acoustic sensor used to detect the point of origin and the point of impact of missiles, IEDs, and missiles.
[8] Other applications included use by military or search and rescue teams, by field researchers studying volcanology or seismology, and by other geo-acoustic scientists and engineers.
